IMPROVE!) WA`SHING-MACHINE.

The Schedule referred to in these Letters Patent and making part of thesame.

I, JOHN V. WACKERMAN, ofthe city of BuiTalo, in the county of Erie, andthe State of New York, have invented certain Improvements inWashing-Machines, of which the following is a specification.

The nature of my invention consists in providing a washing-machine witha curved and corrugated metal washing-bed, the same to be operated inconjunction with a rubber, corrugated, and adjustable rubbinghead, thewhole being secured to and on the top of a wash-tub ou which itisIadjustable.

I refer to the drawing which Imakes a part of' this speciication Figure1 represents the washing-machine, in a perspective view.

Figure 2 is a sectional cut through the working parts ofthe`washingmachine.

A iu the drawing is the wash-tub.

The same is provided with two toothed racks, A1, into which tit twocatches, A2, as illustrated in the drawing. Said toothed racks andcatches have for their object to provide for a chance oi' adjusting thewash-bed with itseonnections, so as to make it easy to the operator toWork the same.

B is the curved corrugated metal wash-tub.

The same is-rest-ing on the top of wash-tub A, and is provided with twouprights, B.

C is the rubber' corrugated and adj ust-able rubbing- The same issuspended by means of two suspending rods, D.

Said rods are secured with their lower ends to the rubbing-head C, andwith their upper ends to supporting shaft E, and are provided on theirupper ends with a spiral spring and regulating nut, as plainly seen inthe drawing. The object of said spiral springs and nuts is to adjust thepower required for depressing the corrugated rubber r\1bbing-head,inorder to bring the same in contact with the material to be washed.

It will he observed that the material to be vifashedl is to be placedbetween the curved and corrugated of the 'rack and pawl. This is animportant feature in the invention, as the position of the wash-bed andrubber' materially effect the operation of the latter. Suicient water isheld by the clothes placed between the rubber and bed to wash them.

I am aware that a ratchet or pawl or other equivalent device hasheretofore been employed to move the wash-bed in the box, but heretoforethe device has always been employed in the interior of the box, where itis likely to become inoperative, in consequence of the wash-beds comingin contact with the clothes in the box. Besides, if metal is employedfor the rack and pawl, they are liable to corrode 'from the action ofthe water in the box. i

Myarrangement'of the rack and'pawl on thetop of the box entirelyobviates these objections.

I hereby disclaim' the employment of'a rack and pawl operating in theinterior of the wash-tub; but

What I claim as new, and desire to secureby Letters Patent, is

The wash-tub A, in combination with the corrugated wash-bed B,rubbing-head D, suspending rods D provided with coiled springs E', andnuts and toothed rack Al and catches or pawls A, when said rack andpawls are located omthe top of the sides of the tub A, as constructedand described.
